Detailed Description

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

(Structure of ozone sterilization apparatus 100)

As shown in fig. 1 and 2, an ozone sterilization apparatus 100 according to a preferred embodiment of the present invention includes a control unit 11, a storage unit 12, an operation unit 13, a display unit 14, a communication unit 15, an ozone concentration measurement unit 16, an ozone generation unit 17, a diffusion unit 18, a sensor unit 19, a power supply unit 20, a case body 30, a cover 31 attached to the case body 30, and the like.

The control unit 11 is a part for controlling the operation of the ozone sterilization apparatus 100. Specifically, the ozone sterilization apparatus 100 is configured to include a CPU (Central Processing Unit ), a ROM (Read Only Memory), a RAM (Random Access Memory ), and the like, and to control the respective parts of the ozone sterilization apparatus 100 as a whole by cooperation of a computer program stored in the ROM and the storage unit 12 and the CPU, which are developed in a working area of the RAM.

The control unit 11 measures the elapsed time from the start of the ozone gas generation by the ozone generating unit 17. Here, the control unit 11 functions as a time measurement unit.

The control unit 11 calculates a CT value based on the ozone concentration measured by the ozone concentration measuring unit 16 and the elapsed time measured by the time measuring unit. Here, the control unit 11 functions as a calculation unit.

The control unit 11 obtains, at a predetermined obtaining timing, obtaining data as the ozone concentration measured by the ozone concentration measuring unit 16 and/or the CT value calculated by the calculating unit. Here, the control unit 11 functions as an acquisition unit. Here, the predetermined acquisition timing may be a time interval shorter than a time interval of a storage timing described later.

The control unit 11 also stores the acquired data in an external recording device (described later) via the communication unit 15. Here, the control unit 11 functions as a storage unit.

The storage unit 12 is a storage unit capable of writing and reading data and programs, and is configured by, for example, an HDD (Hard Disk Drive), a semiconductor memory, or the like.

The operation unit 13 receives an operation input from a user, and outputs an operation signal corresponding to the operation input to the control unit 11.

Fig. 3 shows an example of the operation unit 13 and the display unit 14.

As shown in fig. 3, the operation unit 13 includes an ON/OFF button 131, a Concentration button 132, a Level button 133, and a Clear button 134.

The ON/OFF button 131 receives the start or stop of the ozone generating operation of the ozone sterilization apparatus 100.

The Concentration button 132 receives a setting of a target value of the ozone Concentration in the environment where the ozone sterilization apparatus 100 is installed. In the example shown in FIG. 3, the target value of the ozone concentration can be selected from 0.09[ ppm ] and 0.05[ ppm ]. The target value of the ozone concentration can be set to any value as long as it is a low concentration (specifically, 0.10[ ppm ] or less or 0.05[ ppm ] or less, which is a concentration allowed by a human body) that can be used in a human environment.

The Level button 133 receives a setting of the ozone generation amount in the ozone generating section 17. In the example shown in fig. 3, the Level button 133 receives settings of 5 levels of 1 to 5 regarding the ozone generation amount.

Clear button 134 receives a Clear notification (described later) of the maintenance execution timing of ozone sterilization apparatus 100.

The display unit 14 displays various information in accordance with an instruction of a display control signal input from the control unit 11.

As shown in fig. 3, the display unit 14 includes a computed CT value display unit 141, an ON/OFF display unit 142, a Concentration display unit 143, a Level display unit 144, a Clear display unit 145, and an arrival CT value display unit 146.

As shown in fig. 3, the ON/OFF button 131 and the ON/OFF display unit 142, the Concentration button 132 and the Concentration display unit 143, the Level button 133 and the Level display unit 144, the Clear button 134 and the Clear display unit 145 are arranged in one-to-one correspondence in the up-down direction of the paper.

The computed CT value display section 141 displays the CT value computed by the control section 11 (computation section).

When the ON/OFF button 131 is pressed and the ozone generating operation of the ozone sterilization apparatus 100 is ON (after the ozone generating operation is started), the ON/OFF display unit 142 turns ON, for example, a green LED.

The Concentration display unit 143 turns on an LED corresponding to the target value of the ozone Concentration selected by the depression of the Concentration button 132. In the example shown in FIG. 3, the LED corresponding to 0.05[ ppm ] is lit.

The Level display section 144 displays the Level of the ozone generation amount selected by the depression of the Level button 133. In the example shown in fig. 3, "3" in the level of ozone generation amount is displayed.

Clear display 145 turns on the LED in red as a maintenance execution time notification indicating that ozone sterilization device 100 has reached the maintenance execution time. When maintenance is performed by the user and Clear button 134 is pressed, clear display 145 turns on the LED in blue.

The reached CT value display unit 146 turns on an LED corresponding to a predetermined CT value when the CT value calculated by the control unit 11 (calculation unit) reaches the predetermined CT value. In the example shown in fig. 3, LEDs corresponding to the CT values 60 and 330 are turned on.

The communication unit 15 performs data communication with an external device using a predetermined communication protocol under the control of the control unit 11. Specifically, the communication unit 15 is a communication interface including a communication IC (Integrated Circuit ), a communication connector, and the like, and performs data communication with an external device connected by wire or wirelessly via a communication network such as LAN (Local Area Network ), WAN (Wide Area Network, wide area network), or the internet.

As shown in fig. 4, the communication unit 15 includes a port 151 into which a removable storage medium 200 as an external recording device can be inserted. In the example shown in fig. 4, the communication unit 15 includes a port 1511 into which a microSD card (registered trademark) as the removable storage medium 200 can be inserted, and a port 1512 into which a USB (Universal Serial Bus ) (registered trademark) memory as the removable storage medium 200 can be inserted.

The communication unit 15 may have one of the

ports

1511 and 1512.

In addition, other removable storage media may be inserted instead of the microSD card or the USB memory.

In the removable storage medium 200, the time of the storage timing (described later) and the acquired data (described later) as the ozone concentration measured at the storage timing and the computed CT value are stored.

The removable storage medium 200 can be detached from the port 151 after the power supply of the ozone sterilization apparatus 100 is turned OFF.

In addition, the port 151 and the removable storage medium 200 inserted into the port 151 are covered with the cover 31.

Fig. 5A shows a construction view of the cover 31 and the case main body 30 in the vicinity of the cover 31. In addition, FIG. 5B shows a VB-VB cross-section of FIG. 5A.

As shown in fig. 5B, the lid 31 includes a projection 311 and an opening 312. The case body 30 includes a coupling portion 32 coupled to the protruding portion 311.

The protruding portion 311 and the coupling portion 32 are coupled by snap-fit (snap-fit).

The opening 312 is used to detach the protrusion 311 from the coupling portion 32, and the size of the opening is a size that a human finger cannot enter.

The lid 31 and the case body 30 are configured such that the lid 31 can be detached from the case body 30 by inserting a small special tool (for example, a straight screwdriver or the like) that can be inserted into the opening 312 and pushing up the protruding portion 311 to detach the protruding portion 311 and the coupling portion 32.

By adopting the above-described structure for the cover 31 and the case main body 30, the removable storage medium 200 storing data can be configured such that the removable storage medium cannot be easily removed even when the ozone sterilization apparatus 100 is installed in an environment where a large number of persons exist in an indefinite manner.

The ozone concentration measuring unit 16 measures the concentration of ozone in the air in the environment where the ozone sterilization device 100 is installed by an ultraviolet absorption method, a semiconductor film, or the like, and outputs the measurement result to the control unit 11. The method for measuring the ozone concentration is not limited to the above method.

The ozone generating unit 17 generates ozone gas of low concentration (specifically, 0.10[ ppm ] or less or 0.05[ ppm ] or less, which is a concentration acceptable to the human body) that can be used in a human environment by a silent discharge type, an ultraviolet lamp type, a creeping discharge type, or the like under the control of the control unit 11. Further, the method of generating ozone gas is not limited to the above method.

The diffusion unit 18 diffuses the ozone gas generated by the ozone generating unit 17 into the environment in which the ozone sterilization apparatus 100 is installed.

The diffusion unit 18 is, for example, a fan motor, and generates a flow of air by rotating the fan, thereby diffusing ozone gas.

The diffusing unit 18 may be configured to diffuse the ozone gas by an upward flow obtained by heating the air in the ozone sterilization apparatus 100.

In the case where there is a flow of air in the environment where the ozone sterilization apparatus 100 is installed, the ozone sterilization apparatus 100 may not include the diffuser 18.

The sensor unit 19 includes a person sensor 191 and a door opening/closing sensor 192.

The human sensor 191 senses a human to detect the entry and exit of a human in the environment where the ozone sterilization device 100 is installed, and outputs the detection result to the control unit 11. The detection result is temporarily stored in the RAM of the control unit 11.

The door opening/closing sensor 192 is provided in the outer parts of the intake door and the exhaust door of the diffuser 18, detects the open/closed state of the door, and outputs the detection result to the control unit 11. The detection result is temporarily stored in the RAM of the control unit 11.

The power supply unit 20 converts power supplied from the outside into power necessary for each unit in the ozone sterilization apparatus 100 and supplies the power.

(operation of ozone sterilizer 100)

Next, the operation of the ozone sterilization apparatus 100 will be described.

When the user presses the ON/OFF button 131 to receive the start of the ozone generating operation of the ozone sterilization apparatus 100, the control unit 11 starts the log saving process shown in fig. 6.

First, the control unit 11 starts the ozone generating operation, and starts the measurement of the elapsed time from the start of the ozone generating operation (step S1).

The ozone generating operation includes a setting display operation for controlling the ozone generating section 17 to generate ozone gas and controlling the diffusing section 18 to diffuse the generated ozone gas, and for displaying the setting state in the current ozone generating operation on the display section 14.

The control unit 11 turns ON the LED of the ON/OFF display unit 142 as a set display operation in accordance with ON/OFF of the ozone generating operation set by pressing the ON/OFF button 131. Further, the LED of the Concentration display unit 143 corresponding to the target value of the ozone Concentration in the environment where the ozone sterilization apparatus 100 is installed, which is selected by the depression of the Concentration button 132, is turned on. The control unit 11 causes the Level display unit 144 to display the Level of the ozone generation amount in the ozone generation unit 17 set by the depression of the Level button 133. When the ozone sterilization apparatus 100 reaches the maintenance execution time, the control unit 11 turns on the LED of the Clear display unit 145 to red, and otherwise turns on the LED of the Clear display unit 145 to blue.

Next, the control unit 11 determines whether or not the setting in the ozone generating operation is changed by the user' S input operation via the operation unit 13 (step S2). The setting in the ozone generating operation means setting of a target value of the ozone concentration in the environment where the ozone sterilization apparatus 100 is installed, setting of the level of the ozone generating amount in the ozone generating section 17, and clearing of notification of the maintenance execution timing.

When the setting is changed during the ozone generating operation (yes in step S2), the control unit 11 performs the ozone generating operation based on the setting changed in step S2 (step S3).

When the ozone generating operation is performed or the setting is not changed after step S3 is performed (step S2; no), the control unit 11 controls the ozone concentration measuring unit 16 to obtain the ozone concentration in the air in the environment where the ozone sterilization apparatus 100 is installed (step S4).

Next, the control unit 11 determines whether or not the ozone concentration acquired in step S4 is equal to or higher than the set target value of the ozone concentration (step S5).

In step S4, the control unit 11 may acquire the ozone concentration at predetermined intervals (for example, several seconds), calculate an average value of the plurality of measurement results, and determine whether or not the calculated average value is equal to or greater than a set target value of the ozone concentration in step S5.

When the obtained ozone concentration is equal to or higher than the set target value of the ozone concentration (step S5; yes), the control unit 11 stops the generation of the ozone gas by the ozone generating unit 17 and the diffusion of the ozone gas by the diffusing unit 18 (step S6).

When the ozone concentration obtained after the execution of step S6 is smaller than the set target value of the ozone concentration (step S5; no), the control unit 11 calculates a CT value that is a product of the ozone concentration obtained in step S4 and the elapsed time from the start of the ozone generating operation (step S7). In addition, in the case where the execution of step S5 is the 1 st time, step S6a is not executed.

Next, the control unit 11 determines whether or not the storage timing of the concentration of ozone acquired in step S4 and the CT value calculated in step S7 is to be stored (step S8). The storage timing is a time point when a predetermined time (for example, in minutes, specifically, 1 minute) has elapsed since the last storage of the ozone concentration and the CT value.

Since the CT value [ ppm×min ] is calculated by the product of the ozone concentration [ ppm ] and the ozone exposure time (fumigation time) [ min ], the user can further improve the operation efficiency in the verification of the CT value by storing the ozone concentration and the CT value at intervals of the value in minutes, using the stored ozone concentration and CT value.

The predetermined time is not limited to 1 minute, and may be, for example, 10 seconds or 5 minutes.

The predetermined time may be arbitrarily set by the user via the communication unit 15.

If the storage timing is set (yes in step S8), the control unit 11 executes the 1 st data storage process (step S9). Specifically, the control unit 11 stores the time of the storage timing, the ozone concentration acquired in step S4, and the CT value calculated in step S7 in the removable storage medium 200 inserted into the port 151.

Here, the ozone concentration acquired in step S4 and the CT value calculated in step S7 are acquired data.

In step S9, the control unit 11 may store the ozone concentration obtained at the storage timing (for example, at a time point when 1 minute has elapsed since the last time the ozone concentration and CT value were stored), or may store an average value of the plurality of measurement results by obtaining the ozone concentration at predetermined time intervals (for example, several seconds) between the storage timings.

In step S9, the control unit 11 may store, as the acquired data, either one of the ozone concentration acquired in step S4 and the CT value calculated in step S7.

Fig. 7A and 7B show examples of the time of the storage timing and the acquired data stored in the removable storage medium 200.

In the example shown in fig. 7A, the ozone concentration (B) obtained at the storage timing (a) and the calculated CT value (C) are stored.

In the example shown in fig. 7B, the ozone concentration (B) obtained at the storage timing (a), the time of day (D) from the start of the ozone generating operation to the end of the ozone generating operation, and the value (E) obtained by adding up the ozone concentrations obtained during the time period are stored.

In the example shown in fig. 7A and 7B, the storage timing is a time point when 1 minute has elapsed since the last storage of the ozone concentration and the CT value, and thus the stored acquired data is time-series data continuously arranged at 1 minute intervals.

That is, the control unit 11 continuously saves the acquired data to the external recording device at predetermined time intervals. The control unit 11 may control the external recording device to store the acquired data, or may transmit the acquired data to the external recording device to store the acquired data.

As described above, by storing acquired acquisition data in the external recording device at a predetermined acquisition timing, the acquired data can be provided to the user via the external recording device.

Further, since the acquired data stored in the external recording device is time-series data which are sequentially arranged at predetermined time intervals, the acquired data can be provided to the user in a form that enables calculation of the CT value and verification of the CT value.

As described above, the control unit 11 stores the acquired data in the removable storage medium 200 inserted into the port 151 connected to the control unit 11 by wired communication. Therefore, even when a device (for example, a medical device (medical device defined in the 2 nd medical method)) having weak resistance to the near electromagnetic field generated by an RF (Radio Frequency) wireless communication device is provided in the same room in which the ozone sterilization apparatus 100 is provided, the acquired data can be stored without affecting the device.

Further, since the acquired data is stored in the removable storage medium 200, the user can detach only the removable storage medium 200 storing the acquired data from the ozone sterilization apparatus 100 and perform the verification operation of the CT value at a location different from the room where the ozone sterilization apparatus 100 is installed.

When the step S9 is executed or the holding timing is not performed (step S8; no), the control unit 11 determines whether or not the CT value calculated in the step S7 reaches a predetermined CT value (step S10). The predetermined CT value is referred to as CT value 60 or CT value 330 in the example shown in fig. 3.

When the calculated CT value reaches the predetermined CT value (step S10; yes), the control unit 11 turns on the LED corresponding to the predetermined CT value in the reached CT value display unit 146, and notifies the user that the calculated CT value reaches the predetermined CT value.

When the step S11 is performed or the calculated CT value does not reach the predetermined CT value (step S10; no), the control unit 11 determines whether or not the user has pressed the ON/OFF button 131 to receive a stop of the ozone generating operation of the ozone sterilization apparatus 100 (step S11).

When the stop of the ozone generating operation of the ozone sterilization apparatus 100 is received (step S11; yes), the control unit 11 ends the present process.

When the stop of the ozone generating operation of the ozone sterilization apparatus 100 is not received (step S11; no), the control unit 11 shifts the process to step S2.

When the steps S2 to S5 are performed 2 nd and later and the ozone concentration obtained in step S4 is smaller than the set target value of the ozone concentration (step S5; no), if the ozone generation by the ozone generating section 17 and the diffusion of the ozone by the diffusion section 18 are stopped, the control section 11 restarts the generation and the diffusion of the ozone (step S6 a).

Modification 1

Next, modification 1 of the above embodiment will be described.

The following description will focus on differences from the above embodiments. The configuration of the ozone sterilization apparatus 100 according to the present modification is the same as that of the ozone sterilization apparatus 100 according to the above-described embodiment.

In the 1 st data saving process (step S9) of the log saving process of the present modification, the control unit 11 saves the time of the saving timing and the acquired data to the external recording device by the wireless communication method via the communication unit 15.

For example, as shown in fig. 8, when the ozone sterilization device 100 and a dedicated wireless terminal 300 (external recording device) in a room where the ozone sterilization device 100 is installed are connected via the communication unit 15 by Bluetooth (registered trademark), the control unit 11 saves the time of the save timing and the acquired data to the wireless terminal 300 in step S9.

As shown in fig. 8, when the ozone sterilization device 100 and the IoT (Internet of Thing, internet of things) gateway device 400 provided in the room where the ozone sterilization device 100 is provided are connected via the communication unit 15 by Wi-Fi (registered trademark), the control unit 11 stores the time of the storage timing and the acquired data in the external recording device (data server 500) on the cloud via the IoT gateway device 400 in step S9. The user inputs a password from the personal computer 600 and logs in to the data server 500, and can view the data stored in the data server 500 anywhere.

As described above, the acquired data is stored in the external recording device by the wireless communication system via the communication unit 15, so that even when the ozone sterilization apparatus 100 is installed in a place where it is difficult for a human hand to reach, the user can easily acquire the stored acquired data from the external recording device.

In addition, by storing the acquired data in the data server 500 via the IoT gateway device 400, even when the user is not in the room where the ozone sterilization device 100 is installed, the stored acquired data can be checked from the outside.

Modification 2

Next, modification 2 of the above embodiment will be described.

In the log saving process according to the present modification, the control unit 11 executes the 2 nd data saving process shown in fig. 9 instead of the 1 st data saving process.

In the 2 nd data storage processing, first, the control unit 11 acquires the detection result of the human sensor 191 and the detection result of the door opening/closing sensor 192 of the sensor unit 19 in the period from the last storage timing to the present storage timing (step S91 a).

Here, the door opening/closing sensor 192 functions as a detection unit that detects an abnormality in the ozone sterilization apparatus 100.

Next, the control unit 11 obtains a detection result of whether or not an error has occurred in the operation of the diffusion unit 18 in the period from the last storage timing to the present storage timing (step S92 a). The error in the operation of the diffuser 18 refers to insufficient rotation of the fan motor, or the like.

Next, the control unit 11 detects the current operation mode of the ozone sterilization device 100 (step S93 a).

The operation mode in the ozone sterilization apparatus 100 is any one of a warm-up mode, which is a ready state for operating the ozone sterilization apparatus 100 normally, such as immediately after power is turned on, an operation mode, which is a state in which the ozone generating unit 17 generates ozone gas and the diffusing unit 18 diffuses the generated ozone gas, a standby mode, which is a state in which the diffusing unit 18 does not generate ozone gas and operates, and an error mode, which is a state in which the operation of the ozone generating unit 17 and the diffusing unit 18 is stopped due to an abnormality in the ozone concentration measured by the ozone concentration measuring unit 16.

The operation mode may include a target value of the ozone Concentration in the environment where the ozone sterilization device 100 is installed, which is set by pressing the Concentration button 132, and a Level of the ozone generation amount in the ozone generating section 17, which is set by pressing the Level button 133.

Here, the control unit 11 that obtains a detection result of whether or not an error has occurred in the operation of the diffusion unit 18 and detects the operation mode of the ozone sterilization apparatus 100 functions as a detection unit that detects an abnormality in the ozone sterilization apparatus 100.

Next, the control unit 11 associates the detection result of the human sensor 191 and the detection result of the door opening/closing sensor 192 obtained in step S91a, the detection result of the error in the operation of the diffusion unit 18 obtained in step S92a, the detection result of the operation mode of the ozone sterilization device 100 detected in step S93a with the time of the storage timing, the ozone concentration obtained in step S4 of the log storage process, and the CT value calculated in step S7, stores the information in the external recording device (step S94 a), ends the present process, and returns to the log storage process.

In this case, the acquired data are obtained by associating the detection result of the human sensor 191 and the detection result of the door opening/closing sensor 192, the detection result of an error in the operation of the diffuser 18, the detection result of the operation mode of the ozone sterilization apparatus 100, the measured ozone concentration, and the calculated CT value.

The external recording device may be a removable storage medium 200 inserted into the port 151 or may be an external recording device connected by wireless communication via the communication unit 15.

In step S94a of the data storage processing in the above-described 2 nd step, the control unit 11 may store one of the measured ozone concentration and the calculated CT value in association with the detection result of the human sensor 191, the detection result of the door opening/closing sensor 192, the detection result of an error in the operation of the diffusion unit 18, and the detection result of the operation mode of the ozone sterilization apparatus 100.

Fig. 10 shows an example of the time of the storage timing stored in step S94a of the 2 nd data storage process and the acquired data.

In the example shown in fig. 10, similarly to the example shown in fig. 7B, the ozone concentration (B) obtained at the storage timing (a), the time (D) from the start of the ozone generating operation to the end of the ozone generating operation, and the value (E) obtained by adding up the ozone concentrations measured during the time are stored.

Further, as shown in fig. 10, the detection result (F) of the human sensor 191 is stored in the period from the last storage timing to the present storage timing acquired at the storage timing (a). Specifically, as the detection result (F) of the human sensor 191, when the human sensor 191 detects a human, the "detected" is stored, and when the human is Not detected, the "Not detected" is stored.

In addition, the number of times (G) the person sensor 191 detects a person is stored in the time (D) from the start of the ozone generating operation to the end of the ozone generating operation.

Further, as shown in fig. 10, the detection result (H) of the door opening/closing sensor 192 is stored in the period from the last storage timing to the present storage timing acquired at the storage timing (a). Specifically, "Open" is stored when the door opening/closing sensor 192 detects the Open state of the intake door and the exhaust door of the diffuser 18, and "Closed" is stored when the Closed state of the intake door and the exhaust door of the diffuser 18 is detected, as the detection result (H) of the door opening/closing sensor 192.

In addition, the number of times (I) that the door opening/closing sensor 192 detects the open state of the intake door and the exhaust door of the diffuser 18 is stored in the time (D) from the start of the ozone generating operation to the end of the ozone generating operation.

Further, as shown in fig. 10, a detection result (J) of an error (for example, a rotation shortage of the fan motor) in the operation of the diffuser 18 in the period from the last storage timing to the present storage timing acquired at the storage timing (a) is stored. Specifically, as a result (J) of detection of an error in the operation of the diffuser 18, when an error in the operation of the diffuser 18 is detected, "detected" is stored, and when an error in the operation of the diffuser 18 is Not detected, "Not detected" is stored.

In addition, the number of times (K) that an error in the operation of the diffusion section 18 is detected is stored in the time (D) from the start of the ozone generating operation to the end of the ozone generating operation.

Further, as shown in fig. 10, a target value (L) of the ozone concentration in the environment where the ozone sterilization apparatus 100 is installed, a level (M) of the ozone generation amount in the ozone generating section 17, and an operation mode (N) are stored as a result of detection of the operation mode of the ozone sterilization apparatus 100 detected at the storage timing (a). For example, when the operation mode of the ozone sterilization apparatus 100 is the operation mode, as the operation mode (N), the "Running" is stored.

As described above, by storing data (acquired data) obtained by associating the detection result of the sensor unit 19, the detection result of an error in the operation of the diffusion unit 18, the detection result of the operation mode of the ozone sterilization apparatus 100, the acquired ozone concentration, and the calculated CT value, for example, when there is a temporal variation such as a decrease in the ozone concentration in the time-series data of the ozone concentration, the cause of the decrease in the ozone concentration can be determined from these detection results.

Specifically, when the person is detected by the person sensor 191 at the timing when the temporary decrease in ozone concentration is stored, it can be estimated that the temporary decrease in ozone concentration is caused by the entrance and exit of a person in the room where the ozone sterilization apparatus 100 is installed.

Modification 3

Next, modification 3 of the above embodiment will be described.

In the log saving process according to the present modification, the control unit 11 executes the 3 rd data saving process shown in fig. 11 instead of the 1 st data saving process.

In the 3 rd data storage process, first, the control unit 11 temporarily stores the time of the storage timing and the acquired data (the ozone concentration acquired in step S4 of the log storage process and the CT value calculated in step S7) in the RAM of the control unit 11 (step S91 b).

Next, the control unit 11 determines whether or not the time of the storage timing and the number of times of acquiring the data have reached a predetermined number of times (for example, 15 times) in step S91b after the time of the storage timing and the acquired data have been stored in the external recording device last time (step S92 b). The predetermined number of times can be arbitrarily set.

When the time of the save timing and the number of times of acquiring the data reaches a predetermined number of times are temporarily saved (step S92b; yes), the control unit 11 outputs a communication clock for connection to the external recording apparatus by the wireless communication system via the communication unit 15 (step S93 b).

Next, the control unit 11 determines whether or not communication with the external recording apparatus is established (step S94 b).

When communication with the external recording apparatus is not established (step S94b; no), the control unit 11 returns the present process to step S94b. That is, standby is performed before communication with the external recording apparatus is established.

When communication with the external recording apparatus is established (step S94b; yes), the control unit 11 saves the time of the save timing and the acquired data to the external recording apparatus, and then saves the time of the save timing and the acquired data temporarily saved in step S91b a predetermined number of times to the external recording apparatus (step S95 b).

Next, the control unit 11 stops the communication clock (step S96 b), ends the present process, and returns to the log saving process.

As described above, by intensively storing the time of the storage timing and the acquired data stored temporarily a predetermined number of times in the external recording apparatus, the frequency of communication between the ozone sterilization apparatus 100 and the external recording apparatus can be reduced, and by outputting the communication clock only when storing the data in the external recording apparatus, the power consumption of the control unit 11 (CPU) can be suppressed. In the ozone sterilization apparatus 100, in order to generate ozone gas of low concentration and achieve a high CT value, continuous operation is required for a long time, so that it is preferable to suppress the power consumption of the control unit 11 (CPU).

When the time at which the storage timing is temporarily stored and the number of times the data is acquired has not reached the predetermined number of times (step S92b; no), the control unit 11 ends the present process and returns to the log storage process.

Modification 4

Next, modification 4 of the above embodiment will be described.

In the log saving process according to the present modification, the control unit 11 executes the 4 th data saving process shown in fig. 12 instead of the 1 st data saving process.

In the 4 th data storage processing, first, the control unit 11 performs steps S91c to S93c similar to steps S91a to S93a of the 2 nd data storage processing.

Next, the control unit 11 determines whether or not an abnormality is detected based on the detection results of steps S91c to S93c (step S94 c). The abnormality in the detection result is that the person is detected by the person sensor 191 in step S91c, or the open state of the intake door or the exhaust door of the diffusion unit 18 is detected by the door opening/closing sensor 192, or an error in the operation of the diffusion unit 18 is detected in step S92c, or the operation mode of the ozone sterilization apparatus 100 is detected as an error mode in step S93c.

Steps S91c to S94c are abnormality detection operations.

When an abnormality is detected in the detection results (yes in step S94 c), the control unit 11 stores the detection results of the human sensor 191 and the detection results of the door opening/closing sensor 192 obtained in step S91c, the detection results of an error in the operation of the diffuser 18 obtained in step S92c, the detection results of the operation mode of the ozone sterilization apparatus 100 detected in step S93c, the time of the storage timing, the ozone concentration obtained in step S4 of the log storage processing, and the CT value calculated in step S7 in the external recording device (step S95 c), and ends the present processing and returns to the log storage processing.

When no abnormality is detected in the detection result (step S94c; no), the control unit 11 stores the time of the last storage timing and the number of times +1 of abnormality detection operation after the acquired data is stored in the external recording device (step S96 c).

Next, it is determined whether or not the number of times of performing the abnormality detection operation has reached a predetermined number of times (for example, 15 times) after the time of last storing the storage timing and the acquired data in the external recording device (step S97 c). The predetermined number of times can be arbitrarily set.

When the number of times of performing the abnormality detection operation reaches a predetermined number of times (step S97c; yes), the control unit 11 shifts the present process to step S95c.

That is, the control unit 11 (acquisition unit) acquires the detection result of the human sensor 191 and the detection result of the detection unit at the storage timing (at predetermined time intervals). Then, the control unit 11 (storage unit) stores the acquired data in the external recording device when the acquisition unit acquires the detection result that the human sensor 191 does not detect the entry and exit of the human and the detection result that the detection unit does not detect the abnormality a predetermined number of times.

If the number of times of performing the abnormality detection operation has not reached the predetermined number of times (step S97c; no), the control unit 11 ends the present process and returns to the log saving process.

As described above, since the corresponding data (acquired data) is stored in the external recording device only when an abnormality is detected in the detection result or when the number of times of performing the abnormality detection operation reaches a predetermined number of times although no abnormality is detected, the communication frequency between the ozone sterilization device 100 and the external recording device can be reduced, and the power consumption of the control unit 11 (CPU) can be suppressed.

In addition, when there is a variation in the time-series data of the ozone concentration, the cause of the variation in the ozone concentration can be specified based on the abnormality in the detection result, and the amount of the associated data (acquired data) stored in the external recording device can be reduced, so that the capacity of the external recording device can be saved.

The ozone sterilization apparatus 100 according to the present embodiment described above includes: an ozone generating unit 17 that generates ozone gas; an ozone concentration measuring unit 16 for measuring the concentration of ozone in the air; a communication unit 15 that performs data communication with an external recording device (removable storage medium 200, wireless terminal 300, data server 500); an acquisition unit (control unit 11) that acquires acquisition data, which is the ozone concentration measured by the ozone concentration measurement unit 16, at a predetermined acquisition timing; and a storage unit (control unit 11) for storing the acquired data in an external recording device via the communication unit 15.

Therefore, by storing the acquired acquisition data in the external recording device at a predetermined acquisition timing, the acquired data can be provided to the user via the external recording device, and the user can more effectively manage sterilization by ozone based on the acquired data.

The ozone sterilization apparatus 100 according to the present embodiment includes: an ozone generating unit 17 that generates ozone gas; an ozone concentration measuring unit 16 for measuring the concentration of ozone in the air; a time measuring unit (control unit 11) for measuring an elapsed time from the start of the generation of ozone gas by the ozone generating unit 17; a calculating unit (control unit 11) for calculating a CT value based on the ozone concentration measured by the ozone concentration measuring unit 16 and the elapsed time measured by the time measuring unit; a communication unit 15 for performing data communication with an external recording device; an acquisition unit (control unit 11) that acquires acquisition data, which is the ozone concentration measured by the ozone concentration measurement unit 16 and/or the CT value calculated by the calculation unit, at a predetermined acquisition timing; and a storage unit (control unit 11) for storing the acquired data in an external recording device via the communication unit 15.

The ozone sterilization apparatus 100 according to the present embodiment includes: a person sensor 191 for detecting the entrance and exit of a person; and a detection unit (control unit 11, door opening/closing sensor 192) for detecting an abnormality in the ozone sterilization apparatus 100, wherein the storage unit stores data obtained by associating the detection result of the human sensor 191 and/or the detection result of the detection unit with the ozone concentration measured by the ozone concentration measuring unit 16 and/or the CT value calculated by the calculating unit as acquired data in an external recording device.

Therefore, when there is a temporal variation such as a decrease in the ozone concentration in the time-series data of the ozone concentration, the cause of the decrease in the ozone concentration can be determined from the detection result of the sensor unit 19, the detection result of an error in the operation of the diffusion unit 18, and the detection result of the operation mode of the ozone sterilization apparatus 100.

In the ozone sterilization apparatus 100 according to the present embodiment, the acquisition unit acquires the detection result of the human sensor 191 and the detection result of the detection unit at predetermined time intervals, and the storage unit stores the acquired data in the external recording device when the acquisition unit acquires the detection result that the human sensor 191 does not detect the entry and exit of the human and the detection result that the detection unit does not detect the abnormality a predetermined number of times.

Therefore, the frequency of communication between the ozone sterilization apparatus 100 and the external recording apparatus can be reduced, and the power consumption of the control unit 11 (CPU) can be suppressed.

The ozone sterilization apparatus 100 according to the present embodiment includes: a display unit 14 (computed CT value display unit 141); and a control unit 11 for displaying the CT value calculated by the calculation unit on the display unit 14.

Therefore, the user can grasp the CT value calculated at the predetermined acquisition timing.

In the ozone sterilization apparatus 100 according to the present embodiment, the storage unit continuously stores the acquired data in the external recording device at predetermined time intervals.

Therefore, the acquired data can be provided to the user in a form that enables calculation of the CT value and verification of the CT value.

In the ozone sterilization apparatus 100 according to the present embodiment, the predetermined time is a value in minutes.

Therefore, since the CT value [ ppm×min ] is calculated by the product of the ozone concentration [ ppm ] and the ozone exposure time (fumigation time) [ min ], the user can use the stored ozone concentration and CT value to further improve the operation efficiency in the verification of the CT value by storing the ozone concentration and CT value at time intervals of the value in minutes.

In the ozone sterilization apparatus 100 according to the present embodiment, the predetermined time can be arbitrarily set.

Therefore, the acquired data acquired at an arbitrarily set time interval can be provided to the user.

In the ozone sterilization apparatus 100 according to the present embodiment, the communication unit 15 performs data communication by wireless communication.

Therefore, by storing the acquired data in the external recording device by the wireless communication method, even when the ozone sterilization apparatus 100 is installed at a high place where it is difficult for a human hand to reach, the user can easily acquire the stored acquired data from the external recording device.

In the ozone sterilization apparatus 100 according to the present embodiment, the storage unit stores the acquired data in a cloud server (data server 500) that is an external recording device.

Accordingly, by inputting a password from the personal computer 600 and logging in to the data server 500, the data stored in the data server 500 can be viewed anywhere, and even when the user is not in the room where the ozone sterilization device 100 is installed, the stored acquired data can be confirmed from the outside.

In the ozone sterilization apparatus 100 according to the present embodiment, the communication unit 15 performs data communication by a wired communication system.

Therefore, even when a device (for example, a medical device (medical device defined in the 2 nd of the pharmaceutical method)) having weak resistance to the approaching electromagnetic field generated by the RF wireless communication device is provided in the same room in which the ozone sterilization apparatus 100 is provided, the acquired data can be stored without affecting the device.

In the ozone sterilization apparatus 100 according to the present embodiment, the storage unit stores the acquired data in the removable storage medium 200 as an external recording device.

Therefore, the user can detach only the removable storage medium 200 storing the acquired data from the ozone sterilization apparatus 100, and perform the verification operation of the CT value at a location different from the room in which the ozone sterilization apparatus 100 is installed.

The ozone sterilization apparatus 100 according to the present embodiment includes: a cover 31 covering the removable storage medium 200; and a case body 30 to which the cover 31 is attached, the cover 31 being detachable from the case body 30 by using a special tool.

Therefore, even when the ozone sterilization apparatus 100 is installed in an environment where a large number of persons exist, the removable storage medium 200 storing data cannot be easily removed.

In the ozone sterilization apparatus 100 according to the present embodiment, the ozone gas generated by the ozone generating unit 17 is at a concentration that can be used in a human environment.

Therefore, when ozone sterilization apparatus 100 is continuously operated for a long period of time by generating ozone gas of a low concentration that is a concentration that can be used in a human environment, a user can accurately grasp, for example, a situation where the ozone concentration temporarily decreases.

In the ozone sterilization apparatus 100 according to the present embodiment, the storage unit outputs the communication clock only when the communication unit 15 performs data communication with the external recording apparatus.

Therefore, the power consumption of the control unit 11 (CPU) can be suppressed.

In the ozone sterilization apparatus 100 according to the present embodiment, the storage unit stores a plurality of acquired data acquired during a predetermined period in an external recording device in a concentrated manner.

The description of the present embodiment is an example of a preferred ozone sterilization apparatus according to the present invention, and is not limited thereto.
